Can you use castor oil packs for cancer or not?

I'm reading conflicting things online. Some say to not use castor oil packs for cancer because increasing the lymph flow to the area may spread it and some say it's fine to use the packs and may be helpful. Weren't they often prescribed for cervical cancer? I have possible adenocarcinoma in situ of the cervix and would like to use the packs. My naturopath recommended to use the packs as well. I just wonder why the conflicting information? Tweet
